  1. 1. Development of a Light Weight L2-Cache Controller

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Måns Arildsson; [2022]
    Nyckelord :;

    Sammanfattning : An L2 cache is a device that buffers data in fast memory closer to the Central Processing Unit(CPU) in order to deliver its contents with much lower latency than can otherwise be achieved bymain memory. This provides a substantial performance increase in many systems as the memoryinterface is often a bottleneck. LÄS MER

  3. 2. Onboard computer fault-tolerance detection and mitigation

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Gustav Olofsson; [2020]
    Nyckelord :Onboard Computer; Exceptions; Error Handling; RTOS;

    Sammanfattning : The aim for this thesis is to design a software library responsible for preventing, detecting, handling and logging faults caused by radiation in a representable flight computer system based on the Cobham Gaisler GR740 quad-core LEON4FT processor chip. The LEON processor family is commonly used in space applications and it is based on the open SPARC instruction set and has been extended with fault tolerant features to cope with both on-chip radiation effects as well as upsets in external memory.

  4. 3. Design of a fluid rotaryjoint prototype

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Joakim Tänndal; [2014]
    Nyckelord :Rotary union; Rotary coupling; Flow loss; FRJ; RJ; Vätskeroterskarv; Vätskeroterstycke; Svivel; Roterstycke; Tryckförlust;

    Sammanfattning : This thesis, which has been carried out at the department of research and development at Cobham Antenna Systems, comprises the development of a fluid rotary joint (FRJ) prototype and shall provide a thorough insight in relevant design aspects. Based on input parameters and objectives derived from an actual Cobham project, the possibility of manufacturing a fluid rotary joint in-house has been investigated. LÄS MER
